hey guys, so i took my car out for a 30 minute drive, drove it some what hard at the last 5-10minutes then all the sudden my throttle was cutting in and out. when i got home i heard the sound in the video and almost sh!t my pants, rod knock. i started it two more times and the sound and vibration came back. Checked the spark plugs, and they where completely dry. Weird and good part is when i let it sit for about 30 minutes, came back and the sound was completely gone, i took it out again and did a little burnout and again she was fine. i have a track event this weekend and hoping to avoid that at the track lol. do you guys know what it could be ? the car was sitting for about a month in the snow so could it be bad gas?
